> >>> As CHP, torque, and shoulders turning all the way through contact, who does this, what hitter, what pitch. What might appear to be the shoulders turning through contact, is mostly follow through, and this is after the deceleration of the hips/torso/shoulder and lead arm. Which accelerates the the bat to it's peak velocity.

You will not achieve your best bat speed or highest velocity, because there isn't enough deceleration to funnel the energy completely into the bat. <<<

> I have a couple questions regarding the theory that the bats maximum angular displacement rate is due to the deceleration of the hips/torso/shoulder and lead arm. -- First, let us address the bats angular acceleration due to taking the hands being taken in circular path. If I were to swing a ball around on a string, would you say the ball would continue to accelerate as the hands angular acceleration continues to increase? Or, would you say the balls maximum speed occurred because the hand began to decelerate?

Jack,

Your first question is if you keep applying a force constantly the ball would accelerate to certain speed.

If you used Mike Epstein's tetherball analogy, the tetherball would receive an increase in speed as the string wrapped around the pole. He has a diagram mixing in a linear vector with the rotational vector of the tetherball.

I'm sure you can find it in one of his articles.

As for you tire prong, It lacks explanation power of how the swing works. Without understanding how the whip works, the tire prong would have very little explanation power by itself. Because we are talking about the last link in the chain.

And you have shown throughout the years that you do not understand the whip, and/or what you taught in the past was not how the body creates a whip. And your examples of "your" whip theory, has always been wrong and therefor you have never learned how the whip works.
